Ulcerative Colitis and Alcohol

Is Alcohol Healthy or Not?

The answer could be both. Obviously, alcohol in excess for a long period can cause a range of problems including:

  • alcoholism
  • cirrhosis
  • neurological problems 

On the other hand, people who drink modest amounts of alcohol have a lower risk of developing heart disease.

The issues surrounding ulcerative colitis (UC) and drinking alcohol are even trickier. The answer, just like the disease itself, is complicated.  

Pros

On one hand, a very large study examining the outcomes of 304,000 patients suggested that alcohol may actually have a protective effect. The study came to two main conclusions: Coffee intake didn’t relate to UC and alcohol consumption before a UC diagnosis may lower a persons risk for developing the disease. 

The study design and the way that the authors came to these results have many limitations, but it does raise an interesting point: Could alcohol have a protective effect on ulcerative colitis?

Cons

On the other hand, one study found that alcohol and alcoholic byproducts aggravate inflammatory responses in the gut and make UC worse. The same researchers in another study found that one week of alcohol consumption decreased protective molecules in the gut and increased bowel permeability (both of which are markers of worsening UC).

A study in Japan found that smoking and alcohol were both independently associated with UC flares. 

What Happens When You Drink  

People who drink with UC will experience different outcomes. Some people experience relapse in the form of a severe, acute attack. Others will be at a higher risk of chronic liver injury and ultimately liver failure. A buildup of toxins that damage the gut and liver lining, can cause a substantial liver injury.

Others experience an increased risk of symptoms like:

  • nausea
  • vomiting
  • upper gastrointestinal bleeding
  • diarrhea
  • other similar features 

Alcohol may also interact with the medication you’re taking. This means it can alter the excretion of active drug molecules, leading to liver damage and complications. 

The Bottom Line

The current recommendation is that people with UC should avoid alcohol and smoking. 

That said, it’s not entirely clear from the existing data that modest alcohol consumption is a major trigger for relapse. It’s likely best to avoid alcohol consumption when possible and limit consumption when you do drink.
